NECK-YOKE AND POLE CONNECTION.

SPECIFICATION forming part of Letters Patent No. 724,738, dated April 7, 1903.

Application filed August 29,1902.

. ens, in the county of Bradford and State of Pennsylvania, have invented certain new and useful Improvements in Neck-Yoke and Pole Connections; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to neck-yoke and pole connections; and it consists in a special construction and combination with 'the sameof certain pivotal connections uniting the neck-yoke with the pole, substantially as herein described, and more particularly pointed out in the claims, and whereby many advantages are secured over the. ordinary neck-yoke and its connection with the pole, as hereinafter explained.

It has for its object to provide adevice in which while the neck-yoke can be detached quickly at will yet should the traces become unfastencd the neck yoke cannot be detached from the pole, thereby decreasing the danger which naturally follows from such unfastening of the traces.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.v

Figure 1 is a perspective view of portions of a vehicle-pole and of a neck-yoke with the connection applied to them, but having its two members separated. Fig. 2 is a perspective view of the swiveled eye member, showing its component parts separated. Fig. 3 is a perspective View ofthe plate. Fig. 4 is a vertical longitudinal sectional view of the eye member with its parts assembled. Fig. 5 is a vertical longitudinal sectional view of the pole member. Fig. 6 is a perspective View of a portion of the neck-yoke, omitting the swiveled eye member.

1 designates the neck-yoke, and 2 the vehicle-pole. Mounted upon the neck-yoke 1 is the swiveled eye member 3, which consists of the disk or eye portion 4, having projecting from both sides thereof a segmental body portion 5, one surface of which forms a circular arc, and a cone-shaped bearing 6 is serai No. 121,458.' on model.)

rounding this opening upon'the inner 'side of the attaching-.plate is the annular Vproject-ion l0., When the cone-shaped bearing is fitted into the opening of the attachingplate,the end of said bearing projects slightly from the annular projection 10, and to hold the parts together the said projecting portion of the bearing is hammered back upon the annular projection 10, so as to form an annular lug 1l. The neck-yoke is cut to. form aseat 12 for the attaching-plate, and a large socket 13 is also provided, into which the annular projection 10 upon the inner side of the plate fits, thereby preventing lateral movement of the attaching-plate 8 and consequent 'stress upon the attaching-screws.

The cone-shaped bearing 6 is provided with provide a swiveled eye in which the friction is a minimum.

.The eye member 4: is received Within the bifurcated end-17 of the pole member 2, which end is preferably incased by a ferrule or cap 18, the .end of Which is rounded, as at 19,. and bears against the segmental body portion 5 of the eye member when said member is secured Within said bifurcation. .The bifurcation of the cap 18 only extends about onei half the diameter of the eye or disk A and then opens into a receptacle or socket 19a, being in shape the counterpart of half thedisk 4,-the combined bifurcation and socket being commensurate with the di'sk`4. -lt will thus be seen from this peculiar construction of the ferrule or cap 18 that the inner wall of the socket forms a bearing for the periphery of the eye member. To guardV against accidental detachment of the two members, I provide a pin 20, which is secured to a plate 21, mounted on the cap 18, and projects through IOO a perforation 22 in the upper part of said cap. In actual use my connection may be used either with or Without the pin, as the latter serves merely as a safety attachment.

By this arrangement it will be readily seen A that the eye .member 4 oscillates upon its periphery instead of upon the pin for a pivotal center. The advantages thus derived are, first, the gradual wearing out of the pin or bolt, which is the case with other attachments where an eye is used without other means of connection, is entirely prevented, since I get a wearing-surface in said socket and upon the rounded end of the cap so large that deleterious wear is absolutely prevented; secondly, the socket arrangement renders the eye member self-centering-that is, when merely pressed backward the pin goes in place and completes the lock Without any guidance for the purposeand it is impossible to use it Without a perfect lock, no matter how careless the operator may be, and, thirdly, the fact that the rounded end of the cap engages the segmental body portion of the eye at the same time the wal ls of the socket engage a portion of the periphery of the eye at the opposite side absolutely prevents rattle when in use. The plate 21 is provided with an integral bolt 23, which extends into a spring-housing 24, mounted in an opening in the cap 18, and to hold the plate against lateral movement an integral stud 25 projects into another opening 26 in said cap.

The spring-housing which is herein shown is adapted to protect the spiral spring 26 within it against moisture, and it consists of the housing open at both ends and provided with an interior shoulder 27, against which one end of the spring bears. The bolt 23 of the plate 21 extends through the upper end of the housing and through the spiral spring 26 and is provided with a nut which bears against the other end of the spring. After the plate 21 is secured in place upon the cap the lower end of the housing is sealed, as at 28, and around the upper end of the bolt, between the plate 2l and the cap, is placed a packing 29. It will thus be seen that water is prevented from getting into the housing at either end.

To remove from or fit the neck-yoke to the pole, the front end of the plate 21 is raised and the pin 20 is carried with it, thus permitting the eye 4 to be fitted into or withdrawn from the bifurcated end of the pole.

While I have herein shown my preferred construction, I wish it to be understood that Iam not to be limited to this construction and that any changes in form, proportion, and minor details may be made Within the scope ofthe appended claims without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
